I agree with bethesda. The realism they speak of is difficult to nail down, the choice quote is this.
well, this could really be happening. It?s got this somewhat of a suspension of disbelief, even when we do fantasy stuff.
I find this to be accurate. Realism in gaming/books/movies etc, isn't realism in the sense of finding elements of the real world in the game, Realism in games is defining rules and boundaries and sticking to them for the sake of the gamer. Movies like The Matrix can seem more "real" than a movie by David lynch, even though the matrix is entirely about how reality, is not reality. This is because we see how reality in this fantasy functions, and we go with it.
I don't go WTF when neo starts flying, because I understand WHY he can. The unrealism begins when things happen that you feel shouldn't have. Take manga's like bleach, people started crying foul when certain characters began to beat other characters, how unrealistic it was, because their power levels as defined by the author, were broken in the view of the reader.
Often when I'm playing a western RPG, despite it being a game of dragons, magic, etc etc. It still is bound by some sort of rule set that makes sense, and is feasible in a broad sense. The fantasy elements still are a cohesive system.
JRPG's tend to be less defined in this sense, and more just random stuff which isn't really explained to the degree it is in western RPG's. Often this can become a mess of elements which isn't workable. People like quantifiable elements. People like systems where they can settle their mind into. WRPG's have this more often than JRPG's.
This is of course a massive generalisation, and you will note the interviewed member said so.
Perhaps this is a result of D&D creeping in, due to the heavy rule set and nature of how it's played, very defined circumstances and interaction of fantasy elements. Or perhaps this is also because WRPG's tend to stick more to the straight and narrows than JRPG's.
I'm ignorant as to where JRPG's derive most their influences from, but certainly I feel JRPG's seem less realistic in the sense I outlined.
